Definitions

  • the invention relates to a device for admixing a gas to a gas flowing through a line.
  • a common task in industry is the mixture of two gases, one of which flows through a pipe with a large cross-section.
  • An example of this is wind enrichment in shaft furnaces with oxygen.
  • the resulting mixture should be as homogeneous as possible.
  • the oxygen is usually admixed through an angled pipe which is led into the wind pipe.
  • the angled end of this pipe runs in the direction of the wind pipe and is closed at the end. Bores are distributed over the length of the end piece, from which the oxygen is perpendicular to Axis of the end piece emerges, so it meets the flowing air in the wind pipe vertically. This results in a good mixture of both components.
  • the invention is therefore based on the object of providing a device for admixing a gas to a gas flowing through a line, which ensures that the quality of the mixing of the two gases remains constant over a wide pressure range regardless of the amount of the admixed gas.
  • the invention takes advantage of the fact that a change in the amount of gas to be mixed is always associated with a corresponding pressure change in the pressure of the gas to be mixed. This change in pressure is used to move a spring-loaded piston, which releases further nozzle bores when the pressure increases and closes when the pressure drops. A control effect is thus achieved, which results in better mixing.
  • Line 1 shown in FIG. 1 is the wind line for supplying the combustion air for a shaft furnace. It has a relatively large cross-section compared to the tube 2 used for admixing oxygen.
  • the tube 2 is inserted into the line 1 and angled so that its end piece 8 runs in the direction of the line 1.
  • the direction of flow of the air in line 1 is shown by arrows 3, that of oxygen by arrows 4 and 5.
  • the end piece 8 is closed by a closure 6 and has nozzle bores 7 which are distributed over its length. 2 shows a section through the end piece 8 along the line AA in the region of eight nozzle bores 7, which are evenly distributed over the circumference.
  • a piston 9 loaded by a spring 10 is arranged in the end piece 8.
  • the piston 9 is displaced and releases further nozzle bores 7 or closes them.
  • An adjustment screw 11 is advantageously arranged in the closure 6, with which the spring force can be adjusted.
  • the device according to the invention can hereby be optimally adapted to the respective operating conditions.
  • the device according to the invention is not limited to the admixture of oxygen in the wind conduit of shaft furnaces, but can be used with advantage in all comparable mixing problems.
